The RFG 150 DA has been developed by Alexanderwerk as a slip-on attachment to a universal drive motor of the UM series. The rotor fine granulator is designed to meet the requirements and standards in the pharmaceutical, chemical and primary industry and is made for granulation of dry or slightly moist substances.

The UM universal drive motor has an integrated quick release coupling via which a variety of slip-on attachments can be mounted on the UM. Such attachments may be optionally the grater/shredder PGS 165 A or the rotor fine granulator RFG 150 DA.

Depending on the raw material and screen basket, the throughput can be as high as 600 kg/h. Screen baskets with mesh sizes from 0.63 mm to 3.15 mm are available to achieve different granule geometries.

In comparison Alexanderwerk has developed a patented granulator in Diagonal-Design®, which raises the capacity up to 100 % by increasing the effectiveness of the working area of the screen. This leads to a doubling of throughput and in turn to a very gentle with minimal fines generation. Additionally production costs are reduced and the quality of the final product is increased. In addition, the mobile design provides great flexibility during compaction and allows an easy maintenance

In 1885 Mr. Alexander von der Nahmer established Alexanderwerk Group as an iron foundry with mechanical workshops for the production of different kinds of small machines as well as household appliance.

Through the decades the now closed iron foundry has changed to a worldwide known and appreciated mechanical engineering company. Today Alexanderwerk is a specialist for the development and production of compaction and granulation machines, machines for grating and shredding, customized design and plant construction in the chemical, pharmaceutical and primary industry. Moreover, Alexanderwerk convince its customers with an all-round support, consisting of manufacture, delivery, installation supervision, implementation and maintenance.

Evidence of the company's efforts at constantly continuing to develop its products is provided by patents of the company, which employs around ninety-five people: for example the Combi-Vent-Feeder® technology, which enables the air pressed out of the materials during the compacting process to escape, and the Diagonal-Design® solution, which makes for higher throughput capacities during granulation.

The machines are sold all over the world by Alexanderwerk GmbH as well as many international agencies and distribution partners. The Alexanderwerk Inc. branch in Horsham, Pennsylvania in the USA covers the market in North and Central America. In total the number of employees of the Alexanderwerk Group amounts to 106.

The Alexanderwerk AG is certified in accordance with DIN EN ISO 9001:2008
